I really like your style with the whole cartoony feel
although it's a great piece one of the eyes isn't colored
(that may be purposeful) also, the hair edges are a bit
sharp maybe try to round the sides like where the blue
and the grey meet up at the top of the head.
Also in the future, you could add more detail to the hair.
Again great art.
The straight line on the upper part until the behind part of the head should get some shadings to make it a little hard to see. But the half-half thingy is still there. Just add more of that little extra hair like you made on the upper part of the front hair would be better.
Are you planning to add a mouth or a nose on the head? I think adding a bandage mask would be great but, well it's up to you.
Anyway, goodluck with your set project.
